I am fairly new to vaping. I have and EVOD with ego C battery. I started with menthol juice since I was a light menthol smoker and it was fine at first. I went to a vapor store and tasted some other flavors and bought a vanilla I really love. Problem is it is so thick it keeps gunking up my coils so I have to change it almost every fill. I am hoping someone can tell me how to fix this (maybe add something to the juice) or if there is a good vanilla flavor that is not so thick. Thanks
